The incident was reported to WAtoday.com.au by the teenager's concerned father.

The 19-year-old woman was walking along Rothesay Heights around 1.30pm when she said she became aware that a driver wearing high-vis clothing was kerb crawling behind her, before driving past and circling back.

She became distressed and attempted to throw off her low speed pursuer by going down a quiet side street, only to be followed

At this point, with the young woman in tears, a second vehicle overlapped the one driven by the man in high vis, pulled up alongside the teenager and threw open the passenger door.

The female driver, who had witnessed the alleged stalking urged the upset young woman to jump in. They drove off and saw the Ford also speed away.

Police were called and are now investigating.

The teenager's relieved father praised the actions of the female motorist.

"My daughter was really scared and in tears - she realised she'd made a mistake when she went down a quiet street," he said.

"The man had been circling her in his vehicle for about 10 minutes. I can't thank the woman enough for stepping in when she saw something was wrong. I hate to think what might have happened."

He urged people to be on the lookout for the vehicle and report any sightings to police.
